Runners follow an out-and-back route at the Clo-Cow Half Marathon, which starts and finishes along Petaluma’s Kentucky Street, between B Street and Western Avenue. From there, runners head west along Western, followed by stretches along Chapman Lane, Eastman Lane and Middle 2 Rock Road, all the way out to the turnaround point between Purvine and Succetti Roads. After that, the course then heads back along the same route to the race finish.
